通过几年来的广泛调查表明,枣疯病的发生和分布与传病叶蝉的发生分布密切相关。在山区和丘陵地带,枣疯病的发生较平原地区严重,枣园管理水平不同,病株率也有显著的差异。主要的传病介体橙带拟菱纹叶蝉以卵在枣树上越冬;凹缘菱纹叶蝉主要以成虫在松、柏树上越冬,越冬成虫仍保持较高的传病能力。芝麻也是凹缘菱纹叶蝉嗜食的一种寄主,枣园间作芝麻明显提高了枣树上的虫口密度,延长了在枣树上活动危害的时间。 Through extensive investigations over the past few years, it has been shown that the occurrence and distribution of jujube bark is closely related to the occurrence and distribution of leafhoppers. In mountainous areas and hilly areas, jujube bark was more serious than plain areas, with different levels of management and plant disease rates. The main pathogenic mediator orange tapetus leafhopper oviposit over the winter in the jujube tree; concave edge of the leafhopper mainly adults in the pine, cypress wintering, overwintering adults still maintain a high ability to transmit. Sesame seeds is also a host of concave marginal leafhopper feeding, jujube intercropping sesame seeds significantly increased the density of jujube insects, jujube tree to extend the activities of hazardous time.
